2 Claims. (Cl. 242-18) The object of my invention is to provide a winding machine in which packages of fishline, twine, thread, ribbon, or the like may be progressively wound on adjacent core sections of a single core by means of a single guide supported on a traverse bar.

A further object of my invention is to provide means for locking the guide out of frictional contact with the core, or completed package, in an inoperative position.

My invention comprises, generally, a rotary core support, a reciprocating traverse bar, a core removably held on said core support, as a tube circumferentially weakened at predetermined intervals, a guide on said traverse bar for use in winding successive packages, and a line supply, said guide being positioned to lead the line from the supply to successive core sections.

Practical embodiments of my invention are shown in the accompanying drawing, in. which:

Fig. 1 represents a front elevation of so much of one embodiment of a winding machine as will give an understanding of my invention:

Fig. 2 represents a detail front elevation of a portion of another embodiment of my invention in which a single guide is mounted on asleeve, said sleeve being adjustably mounted along the traverse bar;

Fig. 3 represents a transverse vertical section of the embodiment shown in Fig. 2, and shows the guide locked out of frictional contact with the completed package; and

Fig, 4 represents an elevation of two packages separated from a completed multiple package unit.

A hollow core I, in the present instance a cylindrical tube being weakened circumferentially at predetermined intervals as by perforations 2, is removably held on a rotary tube support, as a sleeve 3, having radially projecting wings 4, said support being fixed on shaft 5.

Tube I is removably held on said support between collar 6 on shaft 5 and a washer I held in contact with tube I by means of a lock nut 8 adapted to receive the thread of screw 9 which is formed integral with an end of shaft 5.

Shaft 5 is rotatably supported in frame I0 and may be driven by any well known or approved means, such as a gear 5*.

Also rotatably supported in frame I8 is a shaft II on which a traverse cam I2 is mounted, said shaft II being driven in any well known or approved manner as, for instance, by the gear II".

A frame I3 is mounted on a casing ll of shaft a tension device, in the present instance, weights I8 suspended on lines I9 led over pulleys 20. Saidpulleys 20 are mounted to rotate on rod 2I which is supported in arms 22 of frame I3. Said lines I9 are attached at the other ends thereof to the guides I5.

Means for locking the guides I5 out of contact either with the completed package or the core in an inoperative position includes a bracket 24 carried by traverse bar I4, and fixed thereon by means of set screws 25. Said bracket is located to engage notches 26 in latch levers 2'I pivoted at 28 on guides I5 to lock said guides.

In the form shown in Fig. 2, a single guide I5 is swingably mounted on a sleeve 28 between a shoulder 30 and said sleeve and a collar 3i, said collar being fastened to said sleeve by means ot a set screw 32. Sleeve 29 is adjustably fastened along traverse bar I by a set screw 33,

Means for maintaining the guide I5 in frictional contact with the package comprises, in this embodiment, an arm 34 affixed at an angle to guide I5 and carrying a counterbalance, as an adjustable weight 35, held thereon by means of set screw 36. The increase in diameter of the package causes the leverage on arm 34 to increase as weight 35 is caused to swing upwardly as the guide I5 is forced outwardly, thus constantly increasing the pressure of the guide on the package.

Means for locking the guide out of frictional contact with the core or package comprises, in this instance, a bent arm 31 carried by sleeve 29, and located to engage the notch 26 in latch lever 21 pivoted at 28 on guide I5.

A single feed supply roll 38 is mounted in any well known or approved manner, and the line or other material is led therefrom to a guide I5.

To produce a progressively wound separable multiple package unit according to Fig. l, the operation is as follows:

Lock nut 8 is unscrewed, washer I removed, and the perforated tube I is slipped over the tube support until one end abuts against collar 8. Washer I is replaced and nut I screwed on until washer I abuts against the other end of tube I. The line or other material is then led from the supply roll 38 to and through a guide l5, then to and around an end section of perforated core I. The remaining guides are locked out of frictional contact with the core. Shafts 5 and II are then driven to rotate core I fixed on the tube support carried by shaft 5, and to actuate traverse bar M respectively, said traverse bar 14 being actuated by the travel of stud or roller l6, aflixed thereto, in the endless groove I! of traverse cam I2 which is fastened on shaft II.

The winding operation is continued until a package containing a desired length of line or other material is completed, as 39.

The guide [5 is then looked out of frictional contact with the package and the line or other material is removed from the locked guide and led to and through the next successive guide which is then unlocked. The winding operation is repeated to produce another package on a core section adjacent the first until the number of packages desired in a unit has been wound.

When the form shown in Fig. 2 is used, the operation for winding the first package is similar to that described above for the form shown in Fig. 1.

Where it is desired to wind the next package, the guide I5 may be locked at the limit of its outward movement. Set screw 33 is then loosened and the sleeve 29 carrying the guide I5 and its locking means is moved laterally along the traverse bar into position for winding the next package. Set screw 33 is tightened to hold the apparatus in its proper position on the traverse bar and the guide is unlocked.

The frictional pressure of the guide IS on the core, or package, may be varied by changing the amount of weight used on the form shownin Fig. l, or by adjusting the weight used as a counterbalance shown in Figs. 2 and 3.

When a unit has been'completed, the winding operation is stopped and the line or other material leading from the supply thereof is severed.

Nut 3 is unscrewed and washer I removed to allow core I and the progressively wound pack- ,ages thereon to be removed as a unit.

The embodiment shown in Fig. 1 and described, but not claimed herein, forms the subject matter of my original application filed February 9, 1938, Serial No. 189,561, (now Pat. No. 2,207,615) of which this is a division.

It is evident that various changes may be made in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention and, hence, I do not intend to limit myself to the particular embodiments herein shown and described.

What I claim is:

1. In a winding machine, a rotary core support, a reciprocating traverse bar, a core removably held on said core support, a manually ad--- justable sleeve mounted on said traverse bar and stationary thereon during winding, 9. line guide swingably mounted on said sleeve, a latch on the guide, a line supply, said guide being positioned to lead the line from the supply to successive core sections, means for rotating the core support and reciprocating the traverse bar to progressively wind packages on adjacent core sections and means carried by said sleeve adapted for coaction with said latch for locking the guide out of contact with the core or finished package.

2. In a winding machine, a rotary core support, a reciprocating traverse bar, a core removably held on said core support, a manually adjustable sleeve mounted on said traverse bar and stationary thereon during winding, a line uide swingably mounted on said sleeve, a latch -on the guide, a line supply, said guide being positioned to lead the line from the supply to successive core sections, means for rotating the core support and reciprocating the traverse bar to progressively wind packages on adjacent core sections, means for holding the guide in yielding frictional contact with the package during the winding thereof, said last named means comprising an adjustable counterbalance, and means carried by the sleeve adapted for coaction with the latch for locking the guide out of contact with the core or finished package.
